PRESSURE SPRAY AND WASHING DEVICE Filed June 15, 1947 r 2 Sheets-Sheet 2 Patented Nov. 7, 1950 UNITED STATES PATENT OFFICE 1 Claim.

Thisinvention relates to a pressure spray and washing device and has for its primary object to.create a spray of washing fluid which may be directed against the sides, or into objects to be washed.

Another object is to produce a continuous directed spray of washing fluid which will cover a relatively large area of the object being washed.

The above and other objects may be attained by employing this invention which embodies among its features a pool of washing liquid; a rotor rotatably mounted above said pool of liquid with its lower portion submerged in the liquid in said pool, paddles extending outwardly from the periphery of the rotor for successive immersion in said liquid as the rotor is rotated and means submerged in the liquid in said pool for cooperating with the paddles in forcing out of the pool the liquid which lies adjacent the periphery of the rotor.

Other features include forming the paddles as spiral blades which extend outwardly from the periphery of the rotor, and for substantially the entire length thereof, in such an arrangement that as the paddles are successively moved through a circular path with the rotor the effects of one paddle will overlap those of the other.

Still other features include means submerged beneath the surface of the pool for cooperation with the paddles in forcing out of the pool the liquid which lies adjacent the periphery of the rotor.

In the drawings- Figure 1 is a plan view of a pressure spray and washing device embodying the features of this invention;

Figure 2 is an end view of the device illustrated in Figure l;

Figure 3 is a transverse sectional view taken substantially along the line 33 of Figure 1;

Figure 4 is a longitudinal sectional view taken substantially along the line 4-4 of Figure 3;

Figure 5 is a perspective view of the rotor illustrating the paddles in detail, and;

Figure 6 is a perspective View of the liquid confining shield.

Referring to the drawings in detail a tank designated generally comprising a substantially semi-circular bottom H closed by end walls I2 is equipped with feet [3 which are designed to hold the tank level with the open side disposed upwardly. Attached at opposite ends to the end' walls I2 are suitable bearings M, and fixed. to" one end" of the tank is a bracket 15 upon which. ai'suitable drive motor I6 is supported. The axis of the drive shaft H" of the drive motor: aligns: with the openings in the bearings M- which in turn; lie along the longitudinal axis of: theatank, [8. previously referred to.

lvfountedl for: rotation in. thebearings 14, in axial alignment with the drive. shaft l l of' the motor I6 is a drive shaft I81 carrying a'rotor designated generally l9; and coupled in a conventional manner as at 20 to the drive shaft lal' isrthe drive shaft. 18 so that the latter will rotate when. the motor [G is energized;

'Iihe rotor I9 above referred to comprises a circular cylindrical body 2| carrying on its periphery a radially spaced group of, paddles 22 each of which is of spiral form and extends throughout the entire length of the circular cylindrical body 2|. As illustrated in the drawings the paddles 22 are arranged so that as the rotor rotates within the tank IQ a paddle constantly is submerged in the liquid contained in the tank. In other words as one paddle dips into the liquid the other is still being withdrawn therefrom so as to produce an uninterrupted stream of liquid from the apparatus.

In order to aid in the discharge of the liquid from the apparatus an arcuate shield 24 is provided and carries adjacent opposite endsslotted brackets 25 through the slots of which adjusting screws 26 project into the end walls l2 of the tank I 0. This shield 24 lies substantially concentric with relation to the body 2| in spaced relation thereto so that as the paddles 22 rotate with the rotor l9 they will pass near the concave side of the shield to cooperate therewith in ejecting the liquid from the pool that lies adjacent the periphery of the rotor.

In order that the direction in which the fluid is ejected from the tank I B may be governed I provide each paddle with deflectors 21. These deflectors 21 project from the advancing faces of their respective paddles and are arranged at varying angles to form pockets in which the liquid is trapped and elevated between the surface of the rotor and the concave side of the shield 24. By arranging the deflectors at varying angles the force of the spray may be governed and its direction of propulsion regulated according to the necessities of the service to be performed. It will be understood of course that the proper rotor is selected having the arrangement of deflectors desired, and introduced into the machine 3 to be coupled to the drive motor H5 in accordance with the work to be performed.

In use it will be understood that with the tank H1 filled with the desired washing and cleansing liquid, and the proper rotor I9 mounted in the bearings l4 and coupled to the drive shaft of the motor l6, when the motor is set in operation the rotor will be driven to cause the paddles 22 to move in a counter-clockwise direction when viewed from Figure 3 and lift the liquid confined between the periphery of the rotor and the concave face of the shield 24. Inasmuch as the rotor is directly coupled to the drive motor l6 it will be evident that it will rotate at the same speed as the speed of rotation of the motor and consequently the spray produced by the device will be ejected from the tank with a force governed only by the speed of rotation of the motor. By selecting the rotor best suited to the purpose, the liquid trapped in the pockets formed by the paddles and the deflectors may be ejected in varying directions according to the angular relation of the deflectors with their respective paddles.

While in the foregoing there has been shown and described the preferred embodiment of this invention it is to be understood that minor changes in the details of construction, combination and arrangement of parts may be resorted to without departing from the spirit and scope of the invention as claimed.

Having described the invention, what is claimed as new is:

A pressure spray washing device comprising a substantially semi-cylindrical trough, semi-circular end walls closing theends of said trough to 4 form a semi-circular container for washing liquid, a bearing mounted on the upper edge of each end Wall midway between opposite ends thereof, a shaft mounted in the bearings to rotate about a horizontal axis which extends longitudinally of the container, an elongated circular cylindrical rotor mounted on said shaft to rotate therewith between opposite end walls of the container, a group of peripherally spaced spiral paddles extending radially from said rotor, longitudinally spaced spray deflectors extending angularly from the leading side of each paddle to form in conjunction therewith and with the rotor a group of liquid receiving pockets, means to rotate the rotor at a substantially constant speed, a curved shield in the container extending between opposite end walls, said shield lying concentric with the rotor and means carried by the end walls and coupled to the shield adjustably to hold said shield radially spaced from the rotor whereby the pressure of the spray created by rotation of the rotor may be varied.
